Listen: Willie Nelson f/ Snoop Dogg "Roll Me Up"

In case you didn't already realize it and/or celebrate, it's every stoner's favorite holiday. Of course, we're referring to 4/20, which every year seems to bring out new smoker anthems from across the musical landscape.

That's particularly true in this new country jam from Willie Nelson, who has teamed with a singing Snoop Dogg for "Roll Me Up." And rather than simply give the song away as a free download, you have to listen to it on Nelson's website as a blunt burns across the screen. Hilarious.

The song also features Jamey Johnson and Kris Kristofferson and it will appear on Nelson's upcoming Heroes album, which drops May 15. You can listen to "Roll Me Up" by clicking the link below.
